THOMAS S. CATLIN', 0F WAVELAND, INDIANA.

GUN SIGHT.

Application filed January 24, 1920. Serial No. 353,750.

T 0 all whom it may concern:

Be it known that I, THOMAS S. CATLIN, a citizen of the United States, residing at VVaVe-land, in the county of Montgomery and State of Indiana, have invented certain new and useful Improvements in Gun Sights; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in gun sights, and has for an object to provide an improved attachment to the present form of gun sights which will enable the marksman to more quickly locate the sights and find the target to the end that quicker and more accurate shooting may result.

Another object of the present invention is to provide an improvement or an attachment for the above-described purpose which will be auxiliary to the usual sights without the necessity of changing the standard construction.

A further object of the present invention resides in providing an improved attachment for gun sights which will be simple in construction and adapted for manufacture at low cost.

With these and further objects in view as will in part hereinafter become apparent and in part be stated, the invention comprises certain novel constructions, combinations and arrangements of parts as subsequently specified and claimed.

In the accompanying drawings,

Figure 9 is a perspective view of a front sight having the invention made in one piece therewith.

Figure 10 is a perspective view of a portion of a gun barrel showing a still further modified form of the invention applied thereto.

Figure 11 is a to plan view of the same.

Figure 12 is a ragmentary, perspective view of a gun barrel showing a rear sight with an improved attachment separated therefrom.

Figure 13 is a front elevation of the rear sight with the attachment assembled thereon, and

Figure 14 is a longitudinal sectional view through Figure 13.

Referring more particularly to the drawings, and for the present to Figures 1 to 4 inclusive, 15 designates a gun barrel of the usual octagonal form and having a front sight 16 made in accordance with the approved form, which consists in a pair of flanges 17 for resting on the upper face of the gun barrel 15, and an upstanding web 18 rising from the central part of the flanges 17.

In accordance with the usual practice, the upper edge of the web 18 is caught by the eye at the apex of the V-shaped notch of the rear sight.

According to this form of the invention, the improved attachment consists in a pair of side plates 19 and 20, preferably formed from the same piece of sheet metal, having a yoke 21 connecting the same at their rear ends; this yoke 21 being formed by bending the sheet metal bar upon itself. The plates 19 and 20 are arranged in parallel relation and are spaced a distance apart suitable for receiving the width of the web 18 of the front gun sight. Wings or vanes 22 and 23 are bent over from the upper longitudinal edges of the side plates 19 and 20, and are adapted to lie in the same horizontal planes when the attachment is fixed to the gun sight, as shown in Figures 1, 2 and 3. The wings or vanes 22 and 23 may also with advamtage be of the same piece of sheet metal as the side plates 19 and 20 and the yoke. The side plates are formed with perforations 24 to receive fastening means 25, such, for instance, as a screw, which also passes through the web 18 of the gun sight 16 to hold the attachment in place thereon. In figure 2, I have shown a vertically elongated slot 26 made substantially centrally in the web 18 to allow for the vertical adjustment of the attachment.

Referring more particularly to Figures 5 to 8 inclusive, the gun barrel 15 and sight 16 are made substantially in the same manner as illustrated in Figures 1 to 3 inclusive and are similarly numbered. However, the attachment takes a different form comprising in this case a plate 27 of metal or other suitable material of a width to extend to opposite sides of the web 18, thus providing wings or vanes 28 and 29. The plate 27 extends freely through a vertically and horizontally elongated slot 30, passing through the web 18 to permit the vertical adjustment of said plate. The plate 27 is supported at opposite sides of the web 18 by suitable means, such, for instance, as the screw bolts 31 and 32, which may be turned in the appropriate direction to raise or lower the plate 27. The bolts 31 and 32, therefore, not only form supports for the plate 27, but also effect its adjustment.

Referring now more particularly to Figure 9, there is here shown a front sight constructed similar to the usual form of such sights, and the parts of which are numbered similarly to the sights shown in the fore going figures. This sight differs from the foregoing in that horizontal wings or vanes 33 and 34 are formed directly thereon out of the same material as the web 18.

Referring now to Figures 10 and 11, a similar octagonal gun barrel 15 is shown as provided with a similar front sight 16 having the upstanding web 18. In this form of the invention the front sight is in nowise modified, but the attachment may be applied to and removed from the gun barrel so that such attachment may be used when desired or removed if its use is not wanted. The wings or vanes 35 and 36 are provided in this case by the pointed and reduced ends of a spring collar or clip 37, which is of a suitable diameter to tightly fit about the gun barrel 15, the spring gripping effect serving to hold the collar or clip in place with the pointed ends of the vanes or wings 35 and 36 in contact with the sides of the web 18.

In Figures 12, 13 and 14 is shown the rear sight, which, according to gone approved form, is formed of a piece of sheet metal 38, attached at one end, as by a screw 39, to the gun barrel 15, and having its front end upturned, as indicated at 40, and having a V notch 41 made centrally therein, through which the bead on the front sight 16 is located. My invention contemplates an attachment for the rear sight 40 which comprises a top plate 42 receivable on the rear sight 40 and adjustable in a vertical direction thereon, as by a screw 43, carried by the top plate 42 engaging a slot 44 made in the sight 40 at one side of the V notch 41. A notch 45 is made in the top plate 42 opening through the lower edge thereof and be ing the complement of the V notch 41, so that the two notches may register when the top plate 42 is located on the rear sight 40 in the manner shown in Figure 13. The notch 45 is preferably rounded at its inner end, as-indicated at 46, to conform more accurately to the curvature of the bead provided by the upper edge of the web 18 of the front sight. The top plate 42 is also preferably provided with a rearwardly turned flange 47 extending from its upper edge.

In use, the wings or vanes in the various forms of the invention are all located on the web 18 of the front sight, and they present to the eye of the marksman a horizontal division line, separating the major body portion of the web 18 from the longitudinal bead formed by the upper edge of such web. This head is indicated at 48 in Figure 9, and is the part of the web 18 which extends above the horizontal plane defined by the vanes or wings 33 and 34. It is this bead 48 that must be located in the crotch of the V-shaped opening 41 of the rear sight 40 and must also be located on the heart or bulls eye of the target in order to secure accurate aim.

It is difiicult with the usual forms of front sights to accurately and quickly locate this bead 48 in the V notch 41, and on the target, as the eye must be given time to adapt itself to the sights after the gun is thrown to the shoulder. With the aid of the vanes, such as I have above described, this adaptation of the eye to the sights will take place more quickly, as the vanes present a relatively large object to attract the eye to the upper edge of the Web 18, namely, the bead 48 which extends above these wings or vanes. The result will be a quicker aim and a more accurate one, so that the object secured by this invention is to combine accuracy with speed in shooting.

The attachment on the front sight may be used with or without the top plate 42, which is combined with the rear sight, but such top plate 42 increases the accuracy and quickness of the aim. The top plate 42 is assembled on the rear sight 40 in the manner shown in Figures 13 and 14, the upper portion of such top plate and the flange 47 acting to close the upper end of the V notch 41 in the rear sight, which is usually left open. Therefore, instead of looking through a V notch, the upper part of which is entirely free and open as done at the present time, the marksman is afforded a small opening indicated at 49 in Figure 13, which is closed on all sides and which, therefore,

33. QEOMETRIOAL hNSTRUMENTb causes him to accurately locate the bead 48 of the front sight in the crotch of the V notch 41. Oftentimes, marksmen erroneously fix the front bead 48 with their eye without elevating the rear part of the gun, so that such bead rests exactly in the crotch of the V-shaped opening 41, with the result of inaccurate aim by being in line with the target but too high. However, the use of the top plate 42 causes the opening 49 to be brought in accurate alinement with the front bead 48, and thus secures accuracy. Moreover, the use of this top plate 42 secures quickness in locating the sights, as the top plate 42 removes other surrounding objects which detract the attention of the eye from the sights.

What is claimed is:

1. A gun sight comprising a main sightdirecting web adapted to upstand vertically from a gun barrel, and a laterally arranged plate engaging and adjustable vertically with respect to said web.

2. A gun sight comprising a main sightdirecting web adapted to upstand vertically from a gun barrel, and a pair of laterally arranged vanes engaging and arranged one at each side of the web and vertically adjustable relative thereto.

3. A gun sight comprising a web adapted to upstand vertically relative to a gun barrel, and an integral plate engaging and adjustable vertically with respect to said web and having laterally outstanding vanes.

4. An improved gun sight including a vertically disposed web having its upper edge forming a bead, and a pair of wings or vanes extending horizontally from said web substantially throughout the length thereof and dividing the bead from the lower portion of the web.

5. An improved gun sight including a web having a bead formed at the upper edge thereof, and horizontal wings adjustably carried by said web.

6. A gun sight comprising a web adapted to upstand vertically with respect to a gun barrel, and an integral plate adjustableiverr tical lyny ifill. respecttosai'd'web and having mam y outstanding vanes, the plate being liormedfiii'to'a yoke extending about one end of the web.

In testimony whereof I afiix my signature in presence of two witnesses.
